Omega Speedmaster winding issue

mbp

Hello, upon further inspection it seems like I ended up with a second set of end links from the OB.
I had initially tried that set of end links for the 50th anniversary flat link bracelet--they fit on my Ultraman just fine (but I had preferred the Forstner slid end links for a tighter fit).

Hello, yes I can do that this weekend.

I just sent this email to my WM regarding my just serviced 52 Seamaster. This thread popping up was serendipity…

Quick question (and a long preface): I wound the watch upon arrival and wind it each morning before I put it on. I never have wound it to its stopping point and I have worn it all day, every day, since receiving it back. It keeps perfect time. This morning it had stopped running in the wee hours. No problem, I just set the time and wound…and wound and wound. I never hit a stopping point. I mean, I carefully wound it for a full 3 minutes. Took a shower and then wound it for at least a hundred turns more. The question: is this normal? Depending on which watch I have on, all will hit a full wind stopping point between 20-40 turns of the crown. Mainspring issue, perhaps?

I have received many compliments on the watch and again, it keeps fabulous time. The winding issue does worry me a bit though. Thoughts?

We’ll see what his response is, but I fear there is a mainspring issue.

I’m going to be absolutely disgusted if I have to send this thing back. The amount of money and time to rebuild this heirloom is voluminous. It's been back to me for only a week…

And the answer…seems there is no winding stop for an automatic. Learn something new everyday.

“There is no positive stop for the winding on an automatic watch. In a manual wind timepiece the mainspring is attached to the barrel wall in one of a number of different ways. This is why when you wind a manual wind watch it will eventually get to a point where it can not be wound any further. A watch fitted with an automatic winding device has a different mainspring and a different type of barrel. In place of a hole or hook or brace at its end which securely attaches the mainspring to the inner wall of the barrel an automatic mainspring has what's known as a bridle. This is basically a forked tongue at the end of the mainspring that simply presses against the barrel wall. Since it is not actually positively attached to the barrel wall this bridle allows the mainspring to slip inside the barrel once it is wound past the point of "full wind". This function is necessary since the mainspring is constantly being wound by the auto wind while you wear the watch. Without this slipping ability the mainspring or the autowind mechanism (or both) would be damaged as the auto wind attempted to continually wind the mainspring once it had been fully wound. Hope this explanation helps.”
